The user’s guide also provides design information including the schematic and Bill of Materials (BOM). 1 Overview The LP8755EVM customer evaluation module demonstrates the integrated circuit LP8755 from TI. The LP8755 is a high-performance, multi-phase step-down converter designed to meet the power management requirements of the latest applications processors in portable applications. The device contains six step-down converter cores, which are bundled together in a 6-phase buck converter. This document covers user software provided with the EVM and design documentation that includes schematics and parts list. Figure 1. LP8755EVM The evaluation module consists of two PCB boards, the LP8755 Evaluation Board, and the USB Interface Board. The boards are of the same size, and the LP8755 board is stacked on top of the USB Interface Board. 4 The LP8755 Evaluation Module SNVU290 – NOVEMBER 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Quick Setup Guide www.ti.com 2 Quick Setup Guide Many of the components on the LP8755 are susceptible to damage by electrostatic discharge (ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling the EVM, including the use of a grounded wrist strap at an approved ESD workstation. On opening the LP8755EVM package, ensure that the following items are included: • LP8755 Evaluation Board • USB Interface Board • USB Cable If any of the items are missing, contact the closest Texas Instruments Product Information Center to inquire about a replacement. 2.1 Installing/Opening the Software The EVM software is controlled through a graphical user interface (GUI). The software communicates with the EVM through an available USB port. The minimum hardware requirements for the EVM software are: • IBM PC-compatible computer running a Microsoft Windows® XP or newer operating system • Available USB port • Mouse The latest downloadable software is available at http://www.ti.com/tool/lp8755evm. Download the zip file onto your local hard drive, then unzip this folder. Make sure the USB Interface Board is connected to the Evaluation Board, and connect the USB Interface Board to the PC with the USB cable. Refer to Figure 1. 1. With the power supply disconnected from the unit under test (UUT), open the un-zipped folder, and click on lp8755_nnn.exe (nnn is the version number) to start the software. 2. On the Evaluation SW window bottom right corner you should see text “USB Board connected”. Refer to Figure 2.

For full-load testing of the LP8755EVM, a DC-power supply capable of at least 10A and 4V is required. 5A is suggested as a practical minimum for partial load. The power supply is connected to the EVM using connector X6. The power supply and cabling must present low impedance to the UUT; the length of power supply cables must be minimized. Remote sense, using connector X7, can be used to compensate for voltage drops in the cabling. With the power supply disconnected from the UUT, set the supply to 3.7V DC and the current limit to 5A minimum. Set the power supply output OFF. Connect the power supply's positive terminal (+) to VIN and negative terminal (-) to GND on UUT (X6 Power-in terminal block). Check that jumpers on the boards are set as shown in Figure 1 (factory default jumper configuration). Set power supply output ON, and then continue with the following steps. 1. On Evaluation software GUI, click on Assert VIOSYS. See Figure 3: Marking “1”. 2. Click on Assert NRST. See Figure 3: Marking “2”. 3. Click on Read Registers button. You should see ready message on green background next to the Read Registers button. See Figure 3: Marking “3”. 4. Check that the GUI indicates "PFM" under "Mode" and "Master; 1/6 Phases Active" under "Multiphase" status. See Figure 3: Marking “4”.The EVM is now ready for testing with default register settings loaded. Figure 3.

The maximum load current is specified as 15A. Be sure to choose the correct wire size when attaching the electronic load. A wire resistance that is too high will cause a voltage drop in the power distribution path which becomes significant compared to the absolute value of the output voltage. Connect an electric load to X0. It is advised that, prior to connecting the load, it be set to sink 0A to avoid power surges or possible shocks. Voltage drop across the PWB traces will yield inaccurate efficiency measurements. For the most accurate voltage measurement at the EVM, use TP16 to measure the input voltage and TP10 to measure the output voltage. To measure the current flowing to/from the UUT, use the current meter of the DC power supply/electric load as long as it is accurate. Some power source ammeters may show offset of several milliamps and thus will yield inaccurate efficiency measurements. In order to perform very accurate Iq measurements on the UUT, remove the input protective Zener diode D1 from the board. When assembled, this diode will cause some leakage, especially on high VIN voltages. Also, the output voltage ADC on the USB Interface Board will load the output of LP8755 with a resistance in order of a hundred of kΩ. The 0Ω resistors between the pads of J23 to J28 on the lower left corner of the EVB may also be removed (see Section 5). 3 GUI Overview The evaluation software has the following tabs: Main, Config, and Advanced. The three tabs together provide the user access to the whole register map of LP8755. 3.1 Main Tab The Main tab has the elemental controls for the EVM and provides a view to the chip status. Starting from top, the main controls are: • Assert VIOSYS: This checkbox will assert 1.8V voltage to LP8755 VIOSYS pin (provided that jumper J6 is placed). This pin will enable the chip internal voltage reference and LDO, release POR, and launch OTP read cycle. The VIOSYS voltage is the reference voltage for the System I2C bus. • Assert NRST: This checkbox will assert 1.8V voltage to LP8755 NRST pin. Asserting NRST will launch power-up sequence. • Assert SW Reset: To perform a complete SW reset to the chip, assert and de-assert this checkbox. See the LP8755 datasheet for explanation of LP8755 reset scenarios. • Assert NSLP: When this bit is asserted it tells LP8755 that the device it is powering is in a high-load condition state. On LP8755 this effectively prevents the bucks from entering the Low-Power PFM Mode (ECO). NOTE: The recommended startup sequence for LP8755 is to first assert VIOSYS, then write all needed configuration bits by using the GUI, and then to assert NRST. NOTE: The NRST pin is the reference for the DVS (Dynamic Voltage Scaling) bus (that is, SmartReflex™ bus). NRST needs to be asserted before the chip will acknowledge any transmission on the DVS bus. The Bucks section provides status information for all the 6 buck cores. The Mode field provides information on each of the buck core and can have any of the values given in Table 1: 8 The LP8755 Evaluation Module SNVU290 – NOVEMBER 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated GUI Overview www.ti.com Table 1. Mode Information Buck Mode Disabled Buck state machine in 'disable' Soft Startup Buck state machine in 'soft startup'. May occur when too much loading is present when powering-up the buck. PWM Pulse Width Modulation PFM Pulse Frequency Modulation ECO PFM with 'low power coasting' mode enabled. This means that lots of analog resources are disabled between PFM bursts. Reaction time to load transients is compromised, while Iq is minimized. Sleeping Multi-phase slave is passive. The "Multi-phase Status" info field tells whether a buck core is configured as a master or slave. The field also tells how many phases are active. An ADC on the USB interface card is connected to measure the output voltage of the buck converter, and this is displayed on GUI. The "System Flags / Interrupts" section gives data on system faults and warnings. If the interrupt is set for any reason the Interrupt active field shall show ‘1’ on red background. The flag causing the interrupt will also be set on the Main tab. Interrupts on LP8755 can only be cleared by writing ‘0’ to associated registers. Any individual flag can be cleared by clicking the Clear button next to each flag field. The USB Interface Board uses an I2C-accessible temperature sensor IC to sense the EVB temperature near the LP8755 IC. This information is presented in the "Board Temperature" field. LP8755 register 0x0D provides a coarse temperature indication of the chip. This info is interpreted into the "Chip Temperature" field when the "Poll Status" option is selected. At the bottom of the GUI window is the "Auto Write" checkbox. If "Auto Write" is checked (default) any checking, un-checking or pull-down menu selections will immediately launch I2C writes to the chip register(s). If not checked, the user can update the chip registers to correspond the configuration selected on the GUI by clicking "Write Registers". If "Poll Status" is selected the software sends a query to the LP8755 at a fixed interval in order to detect the status of the chip, including operation mode, multi-phase status, and output current. If not selected, user can read the registers by applying "Read Registers". On the EVM both System I2C and DVS (Dynamic Voltage Scaling) (that is, SmartReflex) buses can be used to interface the chip. The interface to be used can be selected from the Interface pull-down menu. "Bus Speed" pull-down menu selections are given in Table 2 below and are instantly applied for both buses. Notice that for DVS bus to work, NRST needs to be high. Table 2. I2C-Compatible Bus Support 3.2 Bus Speed Selection Explanation Fast (400 kHz) Fast I2C-compliant operation at 400 kHz Fast++ (3.4 MHz) I2C protocol data transfer with 3.4 MHz clock rate. No writing of master code needed, but can done. Input filters correspond to HS lengths – 10 ns minimum filter length for SCL and SDA: High-Speed (3.4 MHz) HS I2C-compliant data transfer with master codes. Other Tabs and Menus The "Tools" pull-down menu hosts another way of accessing the LP8755 registers. The "Direct Register Access" tool can be used to read or write any register. When using direct register access, un-checking the poll status checkbox is recommended. This way the GUI will only do the reads and writes commanded from the direct access dialog. The "Config" and "Advanced" tabs provide the user with pull-down menus and check-boxes for the part of the register space that is not covered by the Main tab, such as output voltage control. These controls are self-explanatory. Note that for the six-phase converter, only the Buck0 (Master) controls are effective. Please refer to the LP8755 datasheet for explanation of the functions.

The console can be used to access the LP8755 registers. Registers can be read or written simply by referring to the logical registers by their name. The console has a number of integrated macros that are listed in Table 3. Table 3. Console Macros Command Parameters Explanation register_name = register value | - Write a value to writable I2C register or logical register. If no parameter given, will return the current register value. The logical register names are the same as given in the datasheet, and must be in uppercase. wait (time) Example: VSET_B0 = 40 Wait for time given in ms. Useful in loops. advanced Change to advanced user mode. user Return from advanced to regular user mode. vout (buck number) Use the ADC on the USB Interface Board to measure any buck output voltage. Return result to console in volts. iout (buck number) Returns the measured load current of the chosen buck core. i2c_bus sr | sys | - Change serial bus communications from the console and the GUI to be made with the specified bus. If called with no parameter treated as query and current selection is returned. 0x address = data or address[bits] = data I2C read or write command. addr = value examples: 0x12 = 0xaa 0x12[7] = 1 0x12[3:0] = 15 The console supports use of scripts. If a text file containing commands supported by the console is stored in the same folder with the evaluation software executable, then the script can be launched from the console by typing the text file name, like script.txt. For demonstration purposes, the evaluation software comes with a set of scripts, which are loaded when Power Saver, Balanced, or High Performance buttons on the "Advanced" tab are clicked. These scripts (saved as script1.txt, script2.txt and script3.txt) will load a collection of register settings that will save energy, maximize load transient performance, or achieve a balance between the two. Clicking the User button will load a script "script4.txt". By default this file contains a demo which loops through all output voltage settings (VSET_B0). User can modify this file for specific register settings. 10 The LP8755 Evaluation Module SNVU290 – NOVEMBER 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Bill of Materials www.ti.com 4 Bill of Materials Designator Description Manufacturer Part Number Qty. !PCB Printed Circuit Board Any SV600763-001 REV A 1 C001, C201, C301, C501 CAP, CERM, 10µF, 10V, ±10%, X5R, 0603 TDK C1608X5R1A106M 4 C1, C2 CAP, TANT, 220µF, 10V, ±10%, 0.05Ω, 7343-31 SMD AVX TPSD227K010R0050 2 C3, C4 CAP, CERM, 22µF, 10V, ±20%, X5R, 0805 Taiyo Yuden LMK212BJ226MG-T 2 C5, C6 CAP, CERM, 0.1µF, 10V, ±10%, X7R, 0603 Kemet C0603C104K8RACTU 2 C010, C30, C31, C32, C33, C110, C310, C410, C510 CAP, CERM, 22µF, 10V, ±20%, X5R, 0603 Samsung CL10A226MP8NUNE 9 C23, C24 CL03 Series 0201 1000nF 6.3 V 20 % X5R SMD Samsung CL03A105MQ3CSNH 2 C27, C28 CAP, CERM, 0.1µF, 10V, ±10%, X5R, 0402 MuRata GRM155R61A104KA01D 2 D1 Diode, Zener, 5.1V, 5W, SMB Micro Commercial Co SMBJ5338B-TP 1 H1, H2, H3, H4 MACHINE SCREW PAN PHILLIPS 4-40 B&F Fastener Supply NY PMS 440 0050 PH 4 H5, H6, H7, H8 Standoff, Hex, 0.5"L #4-40 Nylon Keystone 1902C 4 H19, H20, H21, H22 M4 CIRC CLEARANCE SPACER 5MM Harwin Inc R40-6710594 4 J1, J6, J8, J9 Header, TH, 100mil, 2x1, Gold plated, 230 mil above insulator Samtec, Inc.

Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard. Since the EVM is not a completed product, it may not meet all applicable regulatory and safety compliance standards (such as UL, CSA, VDE, CE, RoHS and WEEE) which may normally be associated with similar items. You assume full responsibility to determine and/or assure compliance with any such standards and related certifications as may be applicable. You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to perform as described or expected. You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use these EVMs. Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected. Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate Assurance and Indemnity Agreement.
